WILLIAM B. HOUGH, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS,TO PATENTED DEVICES COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.

REINFORCED CONCRETE CONSTRUCTION.

To all whom it may concern:

Be it known that 1, WILLIAM B. HoUoH, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful. Improvements in Reinforced ConcreteConstruction, of which the following is a speci iication.

This invention relates to means for spacing reinforcing bars the properdistance from each other and the desired depth within the concrete bodybeing constructed.

While the invention is applicable to various concrete bodies, it isparticularly well adapted for reinforcing concrete beams, one of theobjects being to provide means arranged to support and space a varyingnumber of reinforcing bars or layers of such bars.

In the accompanying drawings, Figure 1 is a vertical sectional viewshowing a plurality of reinforcing bars supported and spaced within amold or form by means embodying my invention. Fig. 2 is a plan view of aportion of the devices employed. Fig. 3 is a fragmental side elevation.Fig. 1 is a detail perspective View of one of the elements. Fig. 5 is afragmental side elevation illustrating a modified form.

Referring to Fig. 1, the mold or formwork into which the concrete ispoured is indithe mold A near the bottom thereof is a baseplate 1supported and spaced from the bottom of the mold by a series ofll-shaped gage members 2. Pairs of arms 3 extend upwardly from the plate1, said arms, in the present instance, being formed integral with thelegs of the gages 2. In the embodiment herein shown, theplate 1 has aseries of staggered openings or slots 1 therein to receive the staggeredarms 3 of the gage 2, sald gage having shoulders 5 at the lower ends ofthe arms 3 upon which the plate 1 rests. The gage 2 and arms 3 mayconsist of a strip of sheet metal, the shoulders 5 being formed and thearms 3 staggered by cutting away the arms 3 on opposite sides of thegage. The lower row of reinforcing bars B is laid upon the plate l, eaohbar lying between the arms of one of the gages 2. The other rows of barsB are supported by cross-pieces'o each of which rests upon the row ofbars next beneath it and has a plurality of notches 17 Specification ofLetters Patent.

1n its upper edge to receive the bars B. The cross-pieces 6' may be ofany suitable material, being herein shown as pieces of sheet metalstanding edgewise between the pairs of arms To provide room for this,the arms 3 are staggered or positioned at opposite sldes of the strip ofmetal forming the gage 2, as above explained. The inner ends of theslots 4 in the plate 1 are practically in line, and when the arms areinserted through said slots, they spread apart laterally slightly andthe gage tends to assume an inclined position with respect to the plate1, as indicated in dotted lines in Fig. 2. This gives sufiicientclearance between the arms to admit the cross-pieces 6. Such clearancemay, however, be provided in other ways, as by cutting away or notchingthe inner edges of the arms, as indicated at 8 in Fig. 5. The length ofthecross-pieces 6 is preferably substantially the width of the mold A.

As will be seen from Fig. 1, each vertical row of bars B may lie betweenone of the pairs of arms 3. If desired the upper ends of the arms may bebent to embrace the respective bars in the top row.

The number of horizontal rows of bars B to be used may be varied to suitrequirements, it being necessary only to place in position the desirednumber of cross-plates 6. The device is thus very easily assembled.

The portion of the device shown in Fig. 2, namely the base plate 1 andthe gages 2 and arms 3 is a unitary structure, being assembled at thefactory and shipped and handled as a unit. This is a desirable featurein practice.

I do not limit myself to the-exact details herein disclosed, asmodifications within the scope of the appended claims will occur tothose skilled in the art.

I claim as my invention:

1. Reinforced concrete construction com-. prising a base plate having aplurality .of slots therein, a series of gage members supporting saidbase plate and each having a plurality of arms extending through saidslots, a horizontal rowof reinforcing bars resting on .said base plate.each bar lying between and being held from lateral displacement by twoof said arms, a cross-piece resting upon said bars and held by said armsagainst displacement longitudinally of the barsfsaid arms lyin atopposite sides of said cross-piece, an a horizontal row of reinforcingbars supported by said cross-piece.

2. Reinforced-concrete construction comprising a horizontal base, gagemembers supporting said base,- a plurality of pairs of arms extendingupwardly from said base, a horizontal row of reinforcing bars resting onsaid base and spaced apart by said arms, a transverse plate restingonsaid row of bars and disposed edgewise, the respective arms of saidpairs lying closely along opposite sides of said plate and serving tohold the plate in edgewise position and to prevent displacement of theplate longitudinally of the reinforcing bars, and a second horizontalrow of reinforcing bars supported by said transverse plate.

3. Reinforced concrete construction comprising a base plate, a pluralityof gage members supportingsaid plate, a plurality of pairs of armsextending upwardly from said plate, a horizontal row of reinforcing barsresting on said plate, and each positioned between two of said arms, acrosspiece extending transversely of said reinforcing bars and standingedgewise between pairs of said arms, said cross-piece resting upon saidrow of reinforcing bars, and having notches in its upper edge, and asecond row of reinforcing bars resting in said notches. y

4. Reinforced concrete construction com prising a base plate having aplurality of pairs of staggered slots therein, a series of gage memberssupporting said base plate and each having a pair of staggered armsprojecting upwardly through one of said pairs of slots, a plurality ofhorizontal rows of reinforcing bars, said bars lying between pairs ofsaid arms, the lower row of said bars resting on said base plate, andmeans for supporting and spacing the upper rows of said bars.

5. Reinforced concrete construction comprising a base plate having aplurality of pairs of staggered slots therein, a series of gage memberssupporting said base plate and each having a pair of staggered armsprojecting upwardly through one of said palrs of slots, a plurality ofhorizontal rows of reinforcing bars, said bars lying between pairs ofsaid arms, the lower row of said bars resting on said base platep-and aplurality of cross-pieces extending transversely to said bars anddisposed edgewise between the pairs of said staggered arms, each of saidcross-pieces resting upon the row of bars next below and having a seriesof notches in its upper edge adapted to receive another row of bars.

6. Reinforced concrete construction comprising a base plate having aplurality of pairs of staggered slots therein, gage members supportingsaid base plate andeach having a pair of staggered arms extendingupwardly through one of said pairs of slots, a horizontal row ofreinforcing bars resting on said base plate, a transverse plate restingon said row of bars and disposed edgewise between and held by saidstaggered arms, and a second horizontal row of reinforcing barssupported by said cross plate.

7. Reinforced concrete construction comprising a base plate having aplurality ofpairs of openings therein, gage members supporting saidplates and having arms extending upwardly through said openings, 2.horizontal row of reinforcing bars resting on said base plate, a crossplate resting on said horizontal row and extending between pairs of saidarms, said arms being cut away to provide clearance for said crossplate, and a second row of reinforcing bars supported by said crossplate.

In testimony whereof I afiix my signature in the presence of twowitnesses.
